Wall Street Is Hiring Again: Wall Street firms hired nearly 6,000 new workers in the second quarter, the first substantial increase since the 1987 stock market crash sent the industry into recession. The Securities Industry Assn. said employment at New York Stock Exchange member firms rose to 214,925 at the end of June, a 2.8% increase for the year. Wall Street employment had fallen steadily since the stock market collapsed four years ago next month, bringing the roaring ‘80s to an end and triggering more than 50,000 job cuts. Industry analysts and executives said the second-quarter increase was stimulated by robust performances in the stock trading and underwriting markets.
